Reasons why I think Jack Swagger is worthless:
. Is supposed to be a heel but is goofy looking but can't be taken seriously.
. When he left hardly anyone cared
. When he came back hardly anyone cared
. He has good technical ability but isn't really capable of making another wrestler look good in the ring
. Doesn't know how to tell a story in the ring
. is embarrasing on the mic with his lithp
. Doesn't know how to get heat
. Putting him in the ring with another babyface doesn't really do either of them any favours.
. There were already plenty of jobbers on the roster, that can do a better job than swagger and exhibit qualities that Swagger lacks (see above) Gabriel, Kidd, etc
So that's why I think Jack Swagger is worthless.
I'll comment on the bolded parts:
A lot of people can leave and nobody will care. That's the WWE. A lot are expendable. Including upper talent like an Alberto Del Rio or Dolph Ziggler.
He's proven to elevate while in the ring. Maybe not often or of the nature of a Bryan Danielson, but he has the capabilities. One of Kaval's best match in the company was thanks to working with Swagger. Both men fed off each other's styles nicely. Brought out the best in both.
Shena....ns. His matches with Mysterio told very good stories actually. Not to mention the absolute TOPS aka his classic with Christian on 2/24/09. That speaks for itself. It's like Jordan's many Championship rings. It's the only claim you need to bring up.
He got heat when he was in the middle of his push. So easy answer to this is the obvious: give the guy something and apparently the fans will react. That's no different than with a lot of his matches being cut down for time on TV and not getting a chance to really connect. I know he doesn't have charisma, but to say it's impossible to garner any form of heat is false.
I don't really get that point. He's a heel. He's supposed to work vs a face. Unless you're implying EVERY face he could work with has him trumped. Which I can firmly disagree with.
Face jobbers. Sure. Heel jobbers not so much. He's miles ahead of guys like JTG, Colons, or Michael McGillicutty. Only current lower card heel who could rival him is Curt Hawkins. Not much else out there on that front.
